Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides a method for sorting objects that are carried on a trolley on a certain path into a plurality of preset positions on the path. Arbitrary sorting within the range is related to the sorting that is dispensed in the left and right directions depending on the position.

(Prior art and its problems) A conventional conveying device for this type of sorting is to install a tray that can be tilted left and right on each trolley, and each sorting position is such that the tray is placed in the position when the trolley passes. 2. Description of the Related Art There is known an apparatus in which an actuator for overturning is installed and an object to be transported on the tray is discharged in the left and right directions by overturning the tray.

In such a conventional sorting system, the objects to be transported are ejected by overturning the tray, so it is unsuitable for objects to be transported that are susceptible to blockage, and there is also the problem that noise is generated when the tray overturns. Furthermore, it is mechanically complicated and has the disadvantage of being prone to failures, such as the need for a means to return a tray that has fallen to its original position.

(Means for Solving the Problems) The present invention proposes a sorting and conveying device that can solve the above-mentioned problems. A conveyor for sorting to be conveyed in the left and right directions with respect to the traveling direction is installed on each traveling trolley, and each sorting conveyor set in the fixed traveling route is placed at a position where the sorting conveyor wraps around the conveyor. The main feature is that a primary coil that constitutes a linear motor for driving the conveyor is provided together with a secondary conductor plate provided on the moving body.

(Function of the Invention) In the above-mentioned conveying device for sorting according to the present invention, each cart is run with the conveyed objects supported on the conveyor, and the loaded objects are sorted first. When the trolley arrives, the sorting is carried out by energizing the previous linear motor (-secondary coil) to the winding rotating body of the conveyor via the secondary conductor plate provided on the conveyor side of the passing trolley. By applying rotational force to the conveyor and moving the conveyor in a predetermined direction, it is possible to carry out the carried objects in the left and right directions.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

Reference numeral 1 denotes a trolley connected endlessly by a universal joint 2, and the upper sorting is carried out via a supporting horizontal shaft wheel 3 and a vertical shaft roller 4 for steady rest provided on the outside of the shaft center of the wheel 3. is supported by an endless guide rail 7 that forms a transport path 5 and a lower return path 6. 8 is each trolley 1
It is a bellows-shaped cover that covers the connecting part between the two. Reference numeral 9 denotes a linear motor as a means for propelling the bogie, and a secondary conductor plate 1 is attached to the inner side of both side plates 10 of each bogie 1 in parallel with the traveling direction.
1a, llb and the support frame 12 on the guide rail 7
The primary coils 13a, 1 are attached to the secondary conductor plates 11a, llb so as to form an appropriate gap between them.
3b.

A sorting conveyor 14 is installed on each of the carts 1 in a horizontally right and left direction perpendicular to the running direction. This is a slant conveyor in which a slat plate 17 is attached to a pair of circulating winding rotary bodies (cheno) 16.

On the other hand, the above-mentioned upper sorting where each cart 1 runs in a royal position is set at a position 18 at appropriate intervals on the conveyance path 5, and each sorting is placed on both the left and right sides of the position 18. A chute 19 for picking up the transported object is disposed so as to be connected to both discharge ends. Further, a linear motor 20 for driving the sorting conveyor 14 is disposed at each sorting position 18. This linear motor 2
0 is the slat plate 17 on the conveyor 14 for each sorting.
is used as a secondary conductor plate, and when the trolley 1 reaches position 18, each sorting is carried out directly under the lower return path of the slat plate 17 on the conveyor 14. It is provided with primary coils 21 arranged laterally on the left and right so as to form a suitable gear between them and the slat plate 17. This secondary coil 21 is mounted on the support frame 12 on the guide rail 7. A protective cover 22 is made of plastic or the like and covers each secondary coil 13a, 13b, 21 of the seven guide rails.

In the sorting conveyance device configured as described above,
Each secondary coil 13a is installed on the guide rail 7 side of the linear motor 9 for bogie propulsion.

By energizing 13b, a thrust force is applied to the secondary conductor plates 11a and llb on each bogie 1 side in the bogie running direction, and each bogie 1
will run along the guide rail 7 in a predetermined direction. Therefore, the upper sorting is carried out by transferring the conveyed objects W onto the conveyor 14 (on the slat plate 17) on the conveyor 14 (on the slat plate 17), so that the upper sorting is carried out. The objects W can be transported along the route 5, but immediately before each trolley 1 transporting the transported object W reaches a predetermined sorting position 18, the sorting object W is placed at the position 18. By energizing the primary coil 21 of the conveyor drive linear motor 20 in accordance with the required conveyor drive direction (rightward or leftward),
When the trolley 1 reaches the sorting position 18, the secondary coil 21 in the electrically conductive state is placed on the slat plate (secondary conductor plate) 17 on the lower return path of the conveyor 14. are facing each other, slat plate (secondary conductor hand pressure)
A rotational force in a predetermined direction acts on the circulating winding rotating body (cheno) 16 of the current conveyor 14 through the slat plate 17, and each slat plate 17 rotates. As a result, the sorting is carried out on the conveyor 14.
The conveyed object W loaded above is sorted in a predetermined manner at position 18.
Is it the designated person? i7 (rightward or leftward),
It is paid out onto chute 19.

The trolley 1 can also be run in circulation on a horizontal plane, and if the sorting route is not a route, it can also be run along a three-dimensional route. Further, the propulsion means for the trolley 1 is not limited to the linear motor type shown in the embodiment.

Further, a slat conveyor is used as the conveyor 14 for sorting, and the slat plate 17 is also used as the secondary conductor plate of the linear motor 20, but a secondary conductor plate may be provided separately from the slat plate 17. Of course, it is possible to use a conveyor other than a slant conveyor as a conveyor for sorting, but it must have a winding rotating body such as a chain or belt to which a secondary conductor plate of a linear motor can be attached. . Furthermore, the sorting conveyor may be configured to allow sorting only in one direction, either left or right.

(Effects of the Invention) As described above, according to the conveyance device of the present invention, the conveyed objects are carried out laterally on a conveyor on a trolley and sorted, so the conventional overturning tray is not used. Compared to the conventional method, it is possible to sort items smoothly without giving a large shock to the transported items. In addition, there is no noise associated with the overturning of the tray, and there is no need for a means to return the overturned tray to its original position, so the overall mechanism of the equipment becomes extremely simple.

Moreover, since the conveyor is driven by a linear motor that has some coils on the ground side, the carts are smaller and lighter compared to the case where the conveyor drive motor installed on each cart is controlled from the ground side. , it is possible to significantly reduce costs.
